Pay for person living abroad to accommodate one European (7)
I believe the answer is:
expiate
'pay for' is the definition.
(I've seen this before)
'person living abroad to accommodate one european' is the wordplay.
'person living abroad' becomes 'expat' (I've seen this before).
'to accommodate' is an insertion indicator.
'one' becomes 'i' (Roman numeral).
'european' becomes 'e' (abbreviation e.g. EU).
'expat' going around 'i' is 'expiat'.
'expiat'+'e'='EXPIATE'
(Other definitions for expiate that I've seen before include "Make reparation" , "right?" , "Pay for" , "Make up for mistake" , "Do penance, make amends" .)
